Long term variability and correlation study of the blazar 3C 454.3 in radio, NIR and optical wavebands
A. Sarkar, V. R. Chitnis, A. C. Gupta +11
We performed a long-term optical (B, V, R bands), infra-red (J and K bands) and radio band (15, 22, 37 GHz band) study on the flat spectrum radio quasar, 3C 454.3, using the data c…
Properties of radio-loud quasars in Sloan Digital Sky Survey
Haritma Gaur, Minfeng Gu, S. Ramya +1
We present a study of a sample of 223 radio-loud quasars (up to redshift 0.3) in order to investigate their spectral properties. Twenty-six of these radio-loud quasars are ident…
X-ray Intra-day Variability of the TeV Blazar Mrk 421 with Suzaku
Zhongli Zhang, Alok C. Gupta, Haritma Gaur +5
We present X-ray flux and spectral analyses of the three pointed Suzaku observations of the TeV high synchrotron peak blazar Mrk 421 taken throughout its complete operational durat…
Optical Variability of TeV Blazars on long time-scales
Haritma Gaur, Alok C. Gupta, R. Bachev +12
We present the results of photometric observations of three TeV blazars, 3C 66A, S5 0954+658 and BL Lacertae, during the period 2013--2017. Our extensive observations were performe…
